    Oil pump pressure

    I am getting parts together to do a cam swap this winter when the car is off the road. While doing the cam I will be replacing the timing chain, the rocker arms and push rods. I am not sure about replacing the oil pump. My 02 SS has led an easy life in a heated garage, on the road only 7 months a year and I put about 2500 to 3000 miles a year on it. I now have 33k on the clock. My question is do I replace the oil pump ? My guage ( yes I know how inacurate they are ) reads 80 psi cold, 75 psi hot at 3000 rpm, 60 psi hot at idle and never below 50 psi, ever. I am not the first owner so I do not know if I have a stock pump or a ported after market pump. Do I replace something that works fine or do I replace it anyway ?

    +1 If you are going as deep as the timing chain, swap it out for a ported pump. Cheap insurance imo.
